Channel tuned, Channel Locked: BBC1

From the Radio Times:

The Doctor makes a return trip to New Earth, where he and Rose once encountered menacing feline nurses, and patients used as medical guinea pigs. This time he's got new companion Martha in tow, and there's a new threat too - a sinister group known as the Pharmacists are in control. It's not long before Martha finds herself in danger, and the Doctor is set to renew an old acquaintance.

After a slow, awkward start, Gridlock accelerates to its finishing line with important revelations, the dissolving of barriers between the Doctor and his new friend, and an unexpectedly touching reunion with the wise and ancient Face of Boe. Bonuses include some top-hole FX; a still-recognisable Ardal O'Hanlon (even furry cat prosthetics can't hide those twinkly eyes… not to mention the heavy Irish brogue); and a neat reward or two for fans with memories stretching back 40-plus years.

With the football pushing back the start time of this episode (possibly even by one week!), the BBC might just have given away the audience for the week. Then again, the football is sure to attract viewers who may just hang around...

Either way, 'Gridlock' looks to be another outstanding episode. Looking back at the preview, there is what looks like the Ninth Doctor making an appearance. Unfortunately, it definitely isn't him, but I wonder if someone if going around pretending to be the Doctor...

I know also that I haven't posted a review of episode 2 yet, but I will get it posted soon.
